16 Claims.

The invention relates to improvements in bag chutes used in connection with harvester threshers.

Certain types of harvester threshers utilize a bagging platform where the threshed grain is cumulated on the chute and may be discharged from the chute together at the will of the operator, who manipulates a pull rope to release the tail board for that purpose.

The first bag in each accumulation of bags slides the full length of the chute and, as such filled bags are quite heavy, they hit the tail board with considerable force. This is especially true when the machine is traveling a ground slope that increases the normal inclination of the bag chute. Frequently, as the result of such shock, the bags are split open and the grain therein is spilled and wasted. It is desirable, therefore, that some means be provided toovercome this difficulty.

The main object of the invention accordingly is to provide a bag chute having cushion means to absorb the shock of a bag striking the tail board to prevent damage to both the bag and the chute structure.

Another object is to provide such shock absorbing, or minimizing means, which will be simple and fool-proof in operation.

Still another object is to provide such means which functions automatically.

Other objects will be apparent to those skilled in this art as the disclosure is more fully made.

Briefly, such objects may be attained by the illustrative structure herein disclosed in which a bag chute having a tail board is mounted for bodily shifting movement against the resistance of one or more cushion, or recoil, springs, as shown in the accompanying sheets of drawings, wherein:

Figure l is a general perspective view, looking from the front, showing the improved bag chute mounted on the stubbleward side of a hill-side or leveling type of harvester thresher;

Figure 2 is a side elevational view of the harvester thresher and bag chute; and,

Figure 3 is a detail, central, side sectional view through the upper end of the bag chute.

A'harvester thresher of the hill-side type is shown, having a body If! carrying a baggers platform I! and a seat l2, there being an elevator 5 3 for directing threshed grain from the body to a spout l4, beneath which is a bag holder l5 and a bag IS.

The front end of the machine is carried on the usual steering wheel truck ll, while underneath 10 the body is a transverse axle l8 for mounting a wheel on the grainward side of the machine, not shown. The stubbleward'end of this axle carries a longitudinally rearwardly extending pivoted crank arm l9 having its rear end bent trans- 15 versely for mounting a leveling wheel 26 in any usual manner. The improved bag chute will next be described.

Adjacent the platform I I the body ll] carries a transverse, outwardly extending stationary shaft 20 or support 2!, to which is connected a pair of spaced. flat bars 22 that are inclined rearwardly and downwardly. The shaft 2! is suitably braced by braces 23, 24. The bag chute per se comprises an inclined board 25 embraced at its upper 25 end by a U-shaped strap 26 and a similar strap 21 farther down. Between these straps is a third strap 28 having slots 29 through which the bars 22 slidably pass. The straps 26, 21 and 28 carry side boards 3|] for the chute 25. The bars 22 30 thus carry the upper end of the chute from the stationary shaft 2|. Springs 3| are connected to the lower ends of the bars 22, said springs being respectively connected to eyebolts 32 adjustably secured in the strap 21, as shown. By 85 means of these bolts 32, the tension of the springs can be changed as desired.

The cap 33 for the outer end of the hub of the wheel 20 carries a forwardly extending arm 34 having a right angularly and outwardly bent end 40 35, on which is carried a guide roller 36. The lower end ofthe chute board 25 has its under side provided with guides 31, that serve slidingly to carry the lower end of said chute on the roller 36.

By means of a hinge 38, a tail board, or gate, 39 is provided to close the lower end of the chute 25, said tail board having connected to it a forwardly and upwardly extending rod 40, which at its upper end is bent inwardly to form a crank portion 4|. The ends of said'crank portion 4| are carried in the right angle slots 42 formed in guide brackets 43 mounted under the chute 25 at its side edges. The crank 4! is normally pulled by a spring 44 to hold the same up in the vertical portion of the slot 42, thus holding the tail board 39 in chute closing position by means of the rod 48, as shown.

A rockshaft 45 is carried under the chute, said shaft having a cam 46 at one end, and a crank arm 4'! at its other end. A rope 48 accessible to the operator on his station II is connected to the crank 41. When the rope is pulled, the cam 46 pushes the crank 4| down in the slot 42 and the weight of accumulated bags on the chute then releases the tail gate 39 to dump the bags on the ground. As soon as all bags have been thus discharged, the spring 44 is operative to restore the gate 39 and crank 4| to normal bag holding position. The parts 49 are runners to save the chute from damage, should the lower end thereof engage the ground.

From this disclosure it will now be seen that the entire bag chute structure is bodily slidable on the roller 36 and that its weight is resiliently hung from the fixed bars 2| by the recoil springs 3|. Consequently, when the bagger on his platform drops a filled bag of grain on the upper end of the chute 25, it slides down the same by gravity and hits the tail board 39 with considerable force. This force is instantly transformed into a pull that will shift the entire chute structure downwardly against the resistance of the springs 3|. It is thus clear that this shock is absorbed to save the bag from damage. A number of bags are accumulated on the chute and the operator discharges them when he sees fit to do so by pulling the rope 48 to release the tail gate 39, as has already been described.

Thus, an improved bag chute for harvester threshers and the like has been provided to attain the desirable objects heretofore recited.

It is the intention to cover all changes and modifications not departing from the scope of the invention as indicated by the appended claims.
